Figure shows a small angles prism angle `4^(@)`and `mu = (3)/(2)`. A light ray almost normally incident on the prism is refracted and falls on a vertical mirror as shown. Find the total deviation of the ray after reflection from the mirror.

A prism having an apex angle 4^(@) and refractive index 1.5 is located in front of a vertical plane mirror as shown in figure. Through what total angle is the ray is deviated after reflection from the mirror ?

P is small angled prism of angle 3^(@) made of a material of refractive index 1.5 . A ray of light is incident normally to the mirror as shown in figure. M is a plane mirror. The angle of deviation for the ray reflected from the mirror M with respect to the incident ray is :

Light passes symmetrically through a 60^(@) prism of refractive index 1.54. After emergence out from the prism the light ray is incident on a plane mirror fixed to the base of the prism extending beyond it. Find the total deviation of the light ray after reflection from the mirror.

Two plane mirrors at an angle such that a ray incident on a mirror undergoes a total deviation of 240^(@) after two reflections:

Light rays from a source are incident on a glass prism of index of refraction mu and angle of prism alpha At near normal incidence, the angle of deviation of the emerging rays is

A ray of light is incident normally on one of the faces of a prism of apex angle 30 degree and refractive index sqrt2. The angle of deviation of the ray is…degrees.
